2014:Shooter Subteam

To do

To Be Done

• Finish design for Ball constraint in kicker
• Find where we need mechanical stops
• Raise battery
• Locate kicker stop
• Clearance for electrical
• Area (Bottom Pan for electrical between motors
• Side Restraints

Conflicts

• Kicker path and D.T. stabilizers

Design Analysis

Stress Analysis

• An alumninum rod fixed where the bearings are

Current Design

• shooting takes 1-2 seconds
• a kicker strikes the ball through 2 bars (cradle)
• Linked with intake with a motor in the cradle structure pulling and pushing intake

Equipment Requirements/Size

- Weight

• 45 LBS

- CIM motors

• 4 mini CIM
• 2 regular CIM

- Control

• PWM or CAN, but PWM may be preferred as it may be faster
• cRio CAN is derived from RS-232 with max data speed of 115,200 bps.

Sat Jan 11

• Still working on Fundamentals for design

• Calculating how far the kicker has to move

• Calculating if motor driven is possible for Kicker

• met with collection
• integrate our cradle with the collection
• What type of material should we use
• Better to have a longer kicker than a lighter one

Accomplishments/Results

• Kicker must move about 80 - 90 degrees
• If you go any less than that you need more motors
• How to stop kicker motion

• nylon strap

• blocking plate

End of Day Design

Sun Jan 12

• Continue work on 3D design in inventor
• Determine geometry of Our kicker to the ball and cradle
• Our kicker has to be curved at some point so that we get the max speed into the ball rather than rotation
• We Finished drive trains CAD
• Worked on CAD for shooter

Tues Jan 14

• worked more with intake to get a linkage working
• messed some more with the geometry of the shooter
• Made a physical mock-up of the shooter

 *cradle

• kicker

• Worked more on the CAD mock-up
